This invention relates to advertising display devices and particularlyto a magnetically operated device for use in connection with windowdisplays and the like.

The principal object of this invention is a device of the characterdescribed which may be operated from the outside of the display windowby any passerby for the purpose of selectively operating one or moredevices within the display window.

Another object of our invention is to provide an operating device ofthis character part of which may be placed on the inside of the showWindow and part on the outside,

1 these parts cooperating magnetically through the medium of the glass,and withoutany mechanical connection between the parts, as a result ofwhich the necessity of drilling or otherwise cutting the glass or ofmaking electrical or other connections from the outside into the displaywindow or show case is eliminated.

Another advantage of our invention resides in the fact that the operatoris not endangered 1) handling any electric currents which wou d beespecially dangerous were the operator standing on the pavement orground.

A similar advantage is that the operator can operate the device and themachines on display only in a predetermined manner, and cannot in anyway cause damage to the machine by improper operation of or by damagingthe outside operating element.

A more specific object and advantage of our invention is an operatingswitch for this purpose which may be manufactured economically and in alarge variety of forms, and .which may be readily and easily placed inoperating position. and does not require any change in the displaywindow itself.

An other object of our invention is a device arranged to intrigue thepasserby by causing actuations of the machines inside of a displaywindow through the medium of the glass front and with no visibleconnection between the part operated by the passerby and the machineswithin the display Window and to direct his attention to each particularmachine in turn, by permitting operation of each machine selectively bythe passerby himself.

Other objects and advantages will be come apparent from the followingspecification in which reference is made to the drawings by referencenumerals.

In the drawings Fig. 1 is a somewhat diagrammatic illustration of adisplay window with the device in position therein for operating thevarious machines being advertised.

,Fig. 2 is a sectional view of the display window illustrated in Fig. 1and is taken on a plane indicated by the line 22.

Fig. 3 is a front elevation of a form of magnetic switch embodying theprinciples of our invention.

Fig. 4 is a cross sectional view of the switch illustrated in Fig. 3with the operating dial therefor in operating position.

Fig. 5 is an enlarged partial sectional view taken on a plane indicatedby the line 5-5 of Fig. 3.

Fig. 6 is a diagrammatic illustration of one form of circuit used incombination with the switch for operating a large number of machines.

Referring particularly to Figs. 1 and 2 there is illustrated a displaywindow in which are a number of machines designated 2, 3, 4, 5 and 6,which it is desired to operate from the outside of the window. Thedisplay win dow is provided with the usual plate glass front 7 forprotecting and guarding the machines. The switch element of our deviceto which the machine to be operated may be magnetically or electricallyconnected is indicated at 10 and is arranged on the inside of thedisplay window and preferably positioned against the inner face of theglass 7, as better illustrated in Fig. 4. r

A manually operated dial or other movable element 12 is positioned onthe outside of the glass preferablv in alignment with the switch 10 foroperating the switch so that the passerby may selectively operate anyone of the devices in the window from the outside. In this manner hisattention may be more efi'ectively arrested and directed to each of themachines in turn. The elements through the medium of the glass 7 and aregrammatically'illustratedin Fig. 6. 'The connected in no other manner.

As a result of this arrangement the attention or" the operator isretained, inasmuch as he can see no connection between the elements heoperates and the machinesv operated thereby. 7 As mentioned it is oftendesirable to operate selectively one or more of the machines on displayand ha e hei na or o our invention. by way of illustration which isarranged for this purpose. Furthermore, to

more definitely focus the attentionlof the:

operator on the particular machine being operated, we have providedlights 18 connected one in parallel with each machine and positioned toilluminate theparticular machine while it is being operated. By turningthe dial 12 to predetermined positions each of thjemachinesin turn maybe rendered operative andat the same time illuminated, usually byclosing electrical circuits connected withthe respective machines. Byturning the dial 12 to'difierent positions relative tothe switch 10thecircuits to each machine are in turnfopened and closed. Since it isdesirable that the dial 12 return to a normal position'o f rest anddisconnect the machines when the pats serby has'released the 'dial, wemay arrange the switch 10 sothat when the dial returns to its normalposition of rest the switch willconnectthe usual window flood lightswith a source of power and accordingly will disconnect these lights whenany particular machine is being operated.

The dial 12 maybe mounted on any suitable pivot connection in a body 15which is glued onto the glass of the window. The weight 9 is provided onthe dial to overb alance the same and cause 'it to return to a 4predetermined normal poslt on of rest when itisreleased bythe operator.The particular number and arrangement of the machines, light-sandcircuits islargely optional, the above being given'by'way ofillustration of i. an efiiective'display and to better illustrate thefeature of our invention;

'To accomplish these results we prefer to use a switch 110 "such asillustrated in Figs. 3 and 4 and-an electric hookup such as diaswitchiomay be mounted on any'suitable standardl through which the'electricconductors may pass fromthe switch 10 to the respective circuits. In theform illustrated,

the'switch "10 comprises a. circular body 16 on which are mounted aplurality of magnets, for example, three magnets 17, 18 and 19, may beused. These magnets are preferably positioned about 120 apart andequally spaceditrom the center of the circular body. All; the magnetsmaybe identical in form and siihilarly mount edso that. the description'ofthemagnet 1 9 onlymajy be given.

l eierr nst he magn te y e a bar magnet pivotally mounted in a yoke 20which is secured to the circular body 16, the magnet being held betweenthe yoke arms by a pivot 21 so as to swing freely about its pivot. 1-1spring 22 which is shown as a leaf spring is secured intermediate itsends to the magnet 19 or the yoke 20, the free ends of the springengaging the other of the two members so as to yieldably hold the magnetin a predetermined neutral position. Carried byor operably connected tothe magnet 10 is a contactor 23. Arranged at each side of this contactorin the path of movement described thereby as the magnet swings about itspivot are complementary contactors 2a and 25, each ofwhich is connectedin a circuit later to be described. These contactors are preferablydisposed one at each side of thecontactor 23.

In this illustrative form of our invention the magnets 17, 18 and 19 arepositioned with the south poles pointing inwardly toward the center ofthe body 16 and extend radially with the north poles pointing outwardlyfrom the center. The dial 12 carries a magnet 26 which may be a bar orhorseshoe magnet. This magnetis secured to the dial so as to turn therewith. If a single magnet is used it should extend diametricallythroughthe center of the dial with the magnet ends positioned so as todescribecircles through the south pole,

for example, of the ma nets 17 18 and 19a:

ried on the magnet 19 is brought into contact with the contactor 25.Similarly'as the south 7 pole of thelmagnet 28 is disposed in front ofthe south pole of the magnet 19, it repels this pole of the magnet 19,causing the magnet to swing in the opposite direction about its pivot,thus bringing the contactor .3 into contact with the contactor 2%, forpurposes later to be described. r

lVe prefer that the elements 17 18 and 19 be permanent magnets insteadof ordinary iron bars, so that two simple contacts may be obtained foreach element. However, instead of magnetizing the members, 17, 18 and19, these may be of ordinary iron and have only single contact each,andthus be attracted by the magnet to effect this contact. A doublecontact is also possible when these elements are of iron and may beobtained by arranging the magnetic means 26 so that the elements 17 18and 19 are each attracted on one side of the pivot point to the magnet26 to effect one contact and are attracted on the opposite sides of thepivot points to swing the elements inthe opposite direction foreffecting another contact, Again, if the elements 17, 18 and 19 arepermanent magnets, iron elements instead ments it will efi'ect movementthereof. As

stated however, we prefer that both the element 26 and the elements 1718 and 19 be permanent magnets so that a heavier flux is obtainable andoperation better insured.

Referring again to the preferred form of our invention, when the dial 12is rotated each of the magnets 17 18 and 19 will be moved to one or theother of its contact positions, thus closing the circuits and operatinga device in the window. In the case of the heavier machines, forinstance, washing machines, electric fans and the like, a power circuitof 110 Volts is usually required. In machines operating on such acircuit it is usually damaging to the machines to start and stop them Ytoo quickly, and furthermore causes a consid erable are on thecontactors which tends to burn or otherwise deleteriously affect thecontacts and adjacent working parts of the switch. To eliminate thesedisadvantages and I to prevent starting and stopping the machines as thedial is being moved from one position to another, we find it expedientto use a circuit such as will now be described,

. and to provide in the circuit a retarded relay so that not only musteach of the magnets 17 18 and 19 be operated to cause a contact but alsoretained in such position for a short interval before the power circuitwill become operative and start themachine. Since the circuits for eachof the magnets may be the net 26 in front of the south pole of themagnet 19, the like poles will repel each other and consequently themagnet will be swung about its pivot point to the position shown a inFig. 6, bringing the contactor 23 carried by the magnet into contactwith the contactor 24. The magnet 19 may be connected to one side of alow voltage source of electric current and the contactor 24 connected tothe other side, so that upon contact of these elements the circuit iscompleted. Such a circuit could directly operate a device utilizing lowvoltage power supply, but inasmuch as a heavy current would bedetrimental to the parts as described, we prefer to use a higher voltagepower circuit and to operate it from the low voltage circuit. Thecircuit 24. A lead 38 is connected tothe line between the battery andrelay 36 and passes to the coil of theoperating relay 37 and then tweenthe contactor 23 and the contactor 24, a closed circuit is formed fromthe battery through the retarded relay 30 and the oper- Y I ating relay36. The movable cont-actor 40 of the operating relay 36 immediatelycloses the power line 41 connecting the machine tobe operated with oneside of the retarded relay 30, for example, with the movable contact 43.Slightly later the contact43 moves to connect the line 41 to one side ofa source" contactors 23 and 24 in contacting'relation for a shortinterval before closing of the power circuit results.

Thus, as described, the passerby must retain the dial 12 for a shortinterval at one of the operating positions before operation is obtained,and revolving of the dial 12 will not rapidly start and stop eachmachine in turn.

A similar hookup may be used for therelay 37 so that upon contact of thecontactor 23 with the contactor 25 another machine may be operated. Aseparate operating relay is provided for each contact, the retardedrelay being common to all.

The circuits we have shown are illustrative of a number of possiblecircuits which may be used, depending upon the particular device to beoperated, voltage required, etc.

From the foregoing description it is apparent that not only is thepasserby protected from electric currents, but likewise it would beimpossible for him to improperly operate the machine on display.Furthermore, since there is no visible connection be tween the dial andthe switch and since each of the machines may be operated selectively byhim, consequent upon his operating the dial, his attention will beretained and focused directly on each machine in turn.

While we have described our invention particularly adapted to use inconnection with a display window or show case having a glass ortransparent front, obviously it is not necessary that it be limited tothis use, as quite a desirable advertising attraction is afforded byplacing the operating elements in spaced relation with no visibleconnection therebetween. It is pointed out, however, that if a solid andimperforate wall such as the glass 7 used between the switch and thedial, that no ferrous substance should be included in the imperforatewall in a position such as to affect the magnets. Again it may bepointed out that while we prefer to use such a switch to form variouselectric contothe contactor 25. \Vhen the magnet 19 isactuated asdescribed, to cause contact be-:
